MITSUBISHI CNC 3 Function Specifications 3-1 Base functions 3-1-1 Full closed loop control The servo control is all closed loop control using the detector's feedback. "Full closed loop control" is the system that directly detects the machine position using a linear scale, whereas the general "semi-closed loop"...

MDS-D-SVJ3/SPJ3 Series Specifications Manual 3-1 Base functions 3-1-3 Speed command synchronous control This is one of the controls which enable two servo motors to drive the same axis. This is also called "Speed tandem control". The same position command is issued to the 2-axis servo control, and the control is carried out according to each axis' position and speed feedbacks.

MITSUBISHI CNC 3 Function Specifications 3-1-5 Spindle's continuous position loop control Under this control, position loop control is always applied to spindle, including when speed command is issued (in cutting). There is no need for control changeover nor zero point return during orientation and C axis control changeover.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 3-1 Base functions 3-1-6 Coil changeover control A signal output from the spindle drive unit controls the changeover of the low-speed and high-speed specification coils in a spindle motor. The drive unit automatically outputs the coil changeover sequence in accordance with the motor speed. 3-1-7 Gear changeover control This function enables a spindle motor to perform both high-speed light cutting and low-speed heavy cutting by changing the gear ratio between the motor and spindle.

MITSUBISHI CNC 3 Function Specifications 3-2 Servo/Spindle control functions 3-2-1 Torque limit function This control suppresses the motor output torque with the parameter values (SV013, SV014). This function is used for stopper positioning control and stopper reference position establishment, by switching the two setting values.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 3-2 Servo/Spindle control functions 3-2-4 Speed loop PID changeover control This function is used under full-closed loop control. Normally, machine-end position tracking delays compared with the motor-end position. Under full-closed position loop control, machine-end position is used for position feedback. Therefore, the motor-end position tends to advance too much, which may cause overshooting of the machine-end position.

MITSUBISHI CNC 3 Function Specifications 3-2-8 Dual feedback control This function is used under full-closed loop control. When a linear scale is used, the machine-end position, such as a table, is directly detected, which may render the position loop control unstable. With this control, however, high-frequency components are eliminated from the machine-end feedback signals, which will lead to stable control.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 3-2 Servo/Spindle control functions 3-2-11 Spindle output stabilizing control Spindle motor's torque characteristic is suppressed due to voltage saturation in the high-speed rotation range, therefore the current control responsiveness significantly degrades, which may cause excessive current. With this control, however, the current and flux commands are compensated to avoid the voltage saturation so that the current control responsiveness will not degrade.

MITSUBISHI CNC 3 Function Specifications 3-3 Compensation controls 3-3-1 Jitter compensation The load inertia becomes much smaller than usual if the motor position enters the machine backlash when the motor is stopped. Because this means that an extremely large VGN1 is set for the load inertia, vibration may occur. Jitter compensation can suppress the vibration that occurs at the motor stop by ignoring the backlash amount of speed feedback pulses when the speed feedback polarity changes.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 3-3 Compensation controls 3-3-4 Overshooting compensation The phenomenon when the machine position goes past or exceeds the command during feed stopping is called overshooting. In OVS compensation, the overshooting is suppressed by subtracting the torque command set in the parameters when the motor stops.

MITSUBISHI CNC 3 Function Specifications 3-3-6 Lost motion compensation type 2 Servo motor always drives the machine opposing to the frictional force, and the torque which is required to oppose the friction during the axis movement is outputted by I control (Integral control) of the speed loop PI control.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 3-3 Compensation controls 3-3-8 Lost motion compensation type 4 When the difference between static and dynamic friction is large, the friction torque changes sharply at the inversion of the travel direction. When the lost motion type 4 is used together with the type 2 or type 3, the acute change of the friction torque is compensated so that the path accuracy at the travel direction inversion can be enhanced.

MITSUBISHI CNC 3 Function Specifications 3-4 Protection function 3-4-1 Deceleration control at emergency stop When an emergency stop (including NC failure, servo alarm) occurs, the motor will decelerate following the set time constant while maintaining the READY ON state. READY will turn OFF and the dynamic brakes will function after stopping. The deceleration stop can be executed at a shorter distance than the dynamic brakes.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 3-4 Protection function 3-4-4 Collision detection function Collision detection function quickly detects a collision of the motor shaft, and decelerates and stops the motor. This suppresses the generation of an excessive torque in the machine tool, and helps to prevent an abnormal state from occurring.Impact at a collision will not be prevented by using this collision detection function, so this function does not necessarily guarantee that the machine tool will not be damaged or that the machine accuracy will be maintained after a collision.

MITSUBISHI CNC 3 Function Specifications 3-5 Sequence functions 3-5-1 Contactor control function With this function, the contactor ON/OFF command is output from the power supply unit (or servo/spindle drive unit for integrated type) based on the judgement as to whether it is in emergency stop, emergency stop cancel, spindle deceleration and stop or vertical axis drop prevention control, etc.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 3-5 Sequence functions 3-5-4 Specified speed output This function is to output a signal that indicates whether the machine-end speed has exceeded the speed specified with the parameter. With this function, the protection door, etc. can be locked to secure the machine operator when the machine- end speed has exceeded the specified speed.

MITSUBISHI CNC 4 Characteristics (3) Magnetic brake power supply 1. Always install a surge absorber on the brake terminal when using DC OFF. CAUTION 2. Do not pull out the cannon plug while the brake power is ON. The cannon plug pins could be damaged by sparks.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 4-1 Servomotor 4-1-9 Dynamic brake characteristics If a servo alarm that cannot control the motor occurs, the dynamic brakes will function to stop the servomotor regardless of the parameter settings. (1) Deceleration torque The dynamic brake uses the motor as a generator, and obtains the deceleration torque by consuming that energy with the dynamic brake resistance.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 5-1 Servo options (d) Wiring of the battery voltage drop warning output The battery voltage drop warning is detected in the MDS-BTBOX-36 and output to the servo drive unit as digital signal.Connect the battery voltage drop warning signal to one of the servo drive units supported by MDS-BTBOX-36.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 6-6 Surge absorber 6-6 Surge absorber When controlling a magnetic brake of a servomotor in DC OFF circuit, a surge absorber must be installed to protect the relay contacts and brakes. Commonly a varistor is used. (1) Selection of varistor When a varistor is installed in parallel with the coil, the surge voltage can be adsorbed as heat to protect a circuit.

MITSUBISHI CNC 7 Selection 7-1 Selection of the servomotor 7-1-1 Outline It is important to select a servomotor matched to the purpose of the machine that will be installed. If the servomotor and machine to be installed do not match, the motor performance cannot be fully realized, and it will also be difficult to adjust the parameters.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 7-1 Selection of the servomotor 7-1-2 Selection of servomotor capacity The following three elements are used to determine the servomotor capacity. 1. Load inertia ratio 2. Short time characteristics (acceleration/deceleration torque) 3. Continuous characteristics (continuous effective load torque) Carry out appropriate measures, such as increasing the motor capacity, if any of the above conditions is not fulfilled.

MITSUBISHI CNC 7 Selection (2) Short time characteristics In addition to the continuous operation range, the servomotor has the short time operation range that can be used only in a short time such as acceleration/deceleration. This range is expressed by the maximum torque and the torque characteristics.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 7-1 Selection of the servomotor (b) Approximation when using the NC command linear acceleration/deceleration pattern + servo standard position control This is a normal command pattern or servo standard position control method.

MITSUBISHI CNC 7 Selection (c) Approximation when using the NC command linear acceleration/deceleration pattern + servo SHG control (option) This is a servo’s position control method to achieve a normal command pattern and high precision. SHG control improves the position loop gain by stably controlling a delay of the position loop in the servo system.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 7-1 Selection of the servomotor (d) Approximation when using the NC command soft acceleration/deceleration pattern + feed forward (high-speed accuracy) control If the feedforward amount is set properly, the delay of the servo position loop is guaranteed. Therefore, this command acceleration pattern can be approximated to the NC command and does not depend on the servo position control method.

MITSUBISHI CNC 7 Selection (e) Confirmation in the torque characteristics Confirm whether the maximum torque "Ta1" and maximum torque occurrence speed "Nm" required for this acceleration/deceleration pattern calculated in the item "(b)" to "(d)" are in the short time operation range of the torque characteristics.

MDS-D-SVJ3/SPJ3 Series Specifications Manual 7-1 Selection of the servomotor (3) Continuous characteristics A typical operation pattern is assumed, and the motor's continuous effective load torque (Trms) is calculated from the motor shaft conversion and load torque. If numbers <1> to <8> in the following drawing were considered a one cycle operation pattern, the continuous effective load torque is obtained from the root mean square of the torque during each operation, as shown in the expression (7-9).

MDS-D-SVJ3/SPJ3 Series Specifications Manual 7-2 Selection of the spindle motor 7-2 Selection of the spindle motor (1) Calculation of average output for spindle In the machine which carries out the spindle’s acceleration/deceleration frequently (example: tapping center), short-time rating is frequently used, and a rise in temperature become significant on the spindle motor or drive unit.

When the power supply regeneration method is used, consider using the MDS-D-V1/V2, MDS-D-SP/SP2 Series, MDS-DM-SPV Series. Make sure to mount the optional regenerative resistor outside the MDS-D-SPJ3 Series (spindle) unit. POINT A built-in regenerative resistor is not mounted.
